WIRE-ROLLING AND CUTTING DEVICE.

Specification of Letters Patent.

Patented Feb. 1,1921.

Application filed October 15, 1919. Serial No. 330,737.

To all whom it may concern:

Be it known that I, ALEX Srinnrrrls, a citizen of Russia, residing atChicago, county of Cook, and State of 1llinois,have invented certain newand useful Improvements in Vi ire Rolling and Cutting Devices, of whichthe following is a specification.

This invention relates to a wire winding and cutting machine andit hasfor an object to provide a simple andeasily constructed and operateddevice whereby wire coming from drawing dies or otherwise may be rolledupon a suitable spool. or bobbin and separated from the main length.

Other objects relate to the provision of means for grippingthe mainlength of wire andholding it in position after being out, and to theprovision of a novel form of cutting means and a novel mounting for thespool permitting its ready withdrawal when full. a

.For further comprehension of the inven tion, andof the objects andadvantages there of, reference will be had, to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features oi the invention are more particularly set forth.

Figure l ofth drawings is a plan Vl&\V

of awire windingand cutting machine con structed according to myinvention.

The frame of my improved inac fii here shown comprises a flat base 1 ofoblong shape from-which an integralplate-lilre member QeXtends upward,this ,lnen berhavng an angularoi'fset'fi at one end. Forconveniencelshall hereinafter'refer tothe nieniber2, which carries nost of theoperating.

parts, simply as the plate.

1 1s a s de elevation, partly inflongi- Journaled upon plate 2 inavertical row and near theend thereof oppositetothe offset 3,,isaseriesof horizontal stub shaftsfi, upon whlch the spools. 5 are sliolablyfnount e VYhIIBthB shafts project a distance approximately double thelength of the spools to accommodate the back and forwardinovement of thespools as the wire winds thereon. The spools 5, each have a sleeve 6mounted therein and slidable on theshait 4, the latter beinglongitudinally grooved'as at 7, while the sleeve is slotted and pressedinwardly on one side to form a key 8, engaging in this groove. A flatspring 9, is fixed at one end in the key 8, a'ncl'its opposite end has aprojection 10 which extends partly acrossthe outer face oithe spool andprevents displacement of the latter.

These stub-shafts 4, are rotated in unison b means of a crankhandlell ona gear 12 pivoted on the plate 2, and meshing with an idler pinion 13whichmeshes in turn witha second gear l/lon the end of one of the stubshafts,the gear '14 having. eccentrieally connected thereto as at 15 aconnectingrod .16 which also connects withcrank arms 17 on the ends ofthe other stub shafts a.

The wires to be wound are indicated at 18 and are led to theniachinethrough aper tures 19, in the offset 3 and then between grip- I pingdevices which are arranged one "above the other and with a commonoperating Iiieans to act in unison upon all the wires. These rippingdevices each consist ofa disk QOfixd on the, upper endof apin 21slidable in a head 22 on the end of a lever arm 23 fulcrumed as at 24511on studs 25 projecting from the plate "2. spring 26 surrounds eachpinQlhetween 1the1disk20 and head'22 and normally acts to press the diskupward. These disks cooperate with abutment heads 2Tfixed on the plate.

The opposite ends of 1evers23 project thronghslots28in plate Qand are.ivotally connected to a vertical link 29 whih is normally pressedupwardlyby a spring 30 which bears betweenthebase 1 and the lower end ofthelink 2Q. springcateh '32 having a beveledupper faee33 anda handle 34is hired on thebase 1 and is adapted to automatically engage theprojection 31 onthe' link when the link is depressed to operatethegrippers'a common operating handle for the grippers and cutters beingprovided, as will be presently pointed out.

The cutters are arranged on plate 2 a short distance from the grippersjust described and comprise fixed knife blades 35 formed on a verticalbar 36 secured to lugs 37 projecting from the plate 2 and havingdownwardly inclined cutting faces 38. Coiiperating with these fixedknives are the movable knives 39 pivoted as at 40 to projection 41 fromthe plate 2 and having rigidly connected thereto the arms 42 whichproject through slots 43 in theplate 2 and are pivoted to a link 44,similar to the link 36, at their ends. This link 44 is also normallypressed upwardly by a spring 45 which bears against the lower endthereof, a spring catch 47 similar to the catch 32, being adapted toengage a projection 46 on the link when the link is depressed.

Pivoted to the lug 37 to which the knife bar 36 is fastened at its upperend is a handle 48, this handle passing through an open ing 49 in theplate 2. This handle is located between the gripping and cutting devicesand is provided with the oppositely projecting angular fingers 50 and 51which are adapted to engage the upper ends of the respective links 29and 44 to operate the gripping and cutting devices.

Mounted on studs 52 projecting from the plate 2 adjacent the cuttingdevices are a series of grooved rollers 53 over which the wires pass. Apair of cooperating friction straps 54 and 55 are mounted upon the plate2 adjacent the rollers 53 and serve to hold a tension on the wires,these strips being preferably spring-pressed toward each other, in anysuitable manner.

' The manner of operation of my improved 7 .wire winding and cuttingmachine is as 40 follows": 7.

v The wires are led through the openings 19, passing between the fixedand movable mem bers of the grippers, and of the cutters, then over therollers 53 and between the tension straps 54 and 55 to the spools 5 towhich the ends may be secured in any suitable manner. 1' The spoolsarethen rotated to wind the wires thereon by turning erank'handle 11 androtating gear 12, pinion 13 and gear 14, the connecting rod 16 causingall the shafts '4, and the spools mounted thereon, to rotate. Whenthespools are'wound full. the handle 48'is depressed, throwing links 29 and44. downward and causing the knife blades 39 and gripping disks 20 tomove upward, simultaneously severing the wires and gripping the endsthereof. As the links 29v and 44 descend the catches 32 and 47engageover the projections3l and 46, holding the-knives and grippingdisks in operativeposition. After'the spools are removed and new onesplaced on the shafts 4 the catches are released and the operation asjust described repeated.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows:
